Have your ZL1 Dyno'ed because I did and it was a disappointment to find out it was 70+ horsepower less then the factory says the are and General Motors is being no help getting it fixed plus I have had 3 Superchargers and going on my 4th and 2nd set of exhaust.

What? 3 blowers and now needing another one? You have something else going on. If you are taking it to the same dealer [assuming you are] take it to a different one. Once they change one out it should be fixed. GM has changed out hundreds of them including mine and no problems since. I would be very suspicious that whoever is working on your car is actually changing the complete blower out for a new one.

Just to make sure you are taking into account that the dyno # is not the same as the HP listed in the brochure (flywheel HP vs wheel HP)?
